3. Fault Confirmation
__________________
A. Test
(1) Do an operational test of the avionics equipmemt ventilation from the Multipurpose Control and Display Unit (MCDU) (Ref. AMM TASK 21-26-00-710-001).
(a) Make sure that the avionics equipment ventilation system operates correctly.
(b) Make sure that the skin air inlet and outlet valves (15HQ and 22HQ) stay closed.
4. Fault Isolation
_______________
A. If the test confirms the fault:
(1) Remove the two cabin pressure controllers (11HL and 12HL) (Ref. AMM TASK 21-31-34-000-001).
(2) Make sure that the skin air inlet and outlet valves (15HQ and 22HQ) open.

(3) Install the cabin pressure controller 1 (11HL) (Ref. AMM TASK 21-31-34-400-001).
(a) If the skin air inlet and outlet valves close:
(b) If the skin air inlet and outlet valves stay open: 1 Install the cabin pressure controller 2 (12HL) (Ref. AMM TASK
1_ Replace the CONTROLLER-CABIN PRESSURE 1 (11HL) (Ref. AMM TASK
21-31-34-000-001) and (Ref. AMM TASK 21-31-34-400-001).
